BRAF

(redirected from v-raf murine sarcoma viral oncogene homolog B1)

BRAF

A gene on chromsome 7q34 that encodes a protein of the raf/mil family of serine/threonine protein kinases, which plays a role in regulating the MAP kinase/ERKs-signalling pathway, affecting cell division, differentiation and secretion.

Molecular pathology
BRAF mutations are associated with cardiofaciocutaneous syndrome, which is characterised by heart defects, mental retardation and a distinctive facial appearance. Acquired BRAF mutations have been linked to non-Hodgkin lymphoma, colorectal cancer, melanoma, thyroid carcinoma, non-small cell lung carcinoma and adenocarcinoma of lung.
